Effect of energy and protein allowances on the reproductive traits of broiler breeder hens

Broiler breeder hens were fed on diets containing 14.5 or 16.5% crude protein and metabolizable energy (ME) 2300, 2600 or 2900 kcal/kg. There were 6 treatment groups each of 50 hens. Each group was allocated a cockerel. Feeding was restricted to 130 g/hen daily and lasted from 24 weeks to about 12 months old. The levels of protein and ME did not consistently influence hatchability or egg fertility.
